IMPROVEMENT IN ICECREAM FREEZERS.

Specification forming part of LettersmPatent No. 135,474, dated February 4, 1873.

To all whom it may concern:

Beit known that I, GEORGES GU1NoT,of Milton, in the county of Santa Rosa and State of Florida, have invented a new and Improved Ice-Cream Freezer, of which the following is a sp'eccation:

Figure 1 is a vertical central section of my improved ice-cream freezer, the line G C, Fig. 2, indicating the plane of section; Fig. 2 is a horizontal section of the same taken on the line 7c lc, Fig. l; and Fig. 3 is a bottom view partly in section of the rotary cream-holder.

Similar letters of reference indicate corresponding parts.

This invention relates to a new apparatus for producing ice-cream or other substances by the rotation of a cylindrical vessel Within a congealing-substance, and consists in a new general combination of parts, of which the cylindrical cream-holder, the stationary interior scraper, a pair of cog-wheels, and means for centering the cylinder are especially nientionable.

1n the drawing, the letter A represents a cylindrical vessel of suitable size, made of sheet metal or other material, and, by preference, with double walls, so that when it is removed t'rom the freezing-tub it may preserve the cream in a frozen state longer than it 4would if not provided with double walls. B is the containing-tub, made of wood or other material, and of such size that the cylinder A can be conveniently placed therein, as shown. This tub B is provided with a sort of false bottom, O, in which a vertical central pin, a, carrying at its upper end and above the bottom C a disk, b, is centered. This disk serves as a direct support for the cylinder A, and has three-more or lessholes or cavities formed in it for the reception of as many pins,

d, that project downward from the bottom of the vessel A. Thus, when the latter vesselis placed upon the disk b, so that its pins d enter the holes of said disk, the cylinder will be centrally supported in the tub B, and will, when revolved, carry the disk b around with it. The upper part of the vessel A is furthermore guided or centered in an annular plate, e, which is secured in the tub B, as shown. f is a bevel-gear wheel rigidly fastened to the upper end of the cylinder Ae-that is to say, to the cover g of the same. A bevel-wheel, h, which is mounted upon a shaft, D, that hangs in bearings above the cover 'i of the tub, ex-

tends down through said cover and meshes into the teeth of the wheel f, so that when the crank-handle j of the shaft D is rotated by muscular or other power the cylinder A will be more rapidly revolved within the tub, the dierence in the velocity of A depen ding upon the difference of the size of the two bevelwheels. E is a vertical shaft or rod standingin the center of the cylinder A and extending through the top or cover of the same into the cover i of the tub, within which the squared upper end of said rod enters in such manner that it cannot revolve while the cylinder A is being revolved around it. The rod E serves to support directly, and by projecting arms Z, a series of vertical Scrapers m m, which are set obliquely against the direction of rotation of the cylinder.

When the matter to be congealed has been placed within the cylinder A and the latter closed by its cover g and placed upon the disk b, and after the ice or other congealing-substance has been placed within the tub B, around the cylinder A, and the cover c' ap-V plied to and fastened down upon the tub by means of thumb-screws n u or otherwise, the apparatus is ready for operation. The crankhandle j is revolved with suitable rapidity, and the cream thereby carried around, within, and by the cylinder A, being meanwhile thoroughly and constantly plowed and displaced by the scrapers m m, which remain stationaryr within the revolving cylinder. After the cream has been sufficiently congea'led the vessel A can be removed from the tub and conveyed to a suitable place, and another cylinder, A, can be placed within the tub, so that thel operation can be continued ad libz'tum.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An ice-cream freezer, composed of the tub B, rotary disk b, revolving cylinder A, cog-Wheels f h, andjstationary scrapers m m on the stationary rod E, all arranged to operate substantially as herein vshown and described.

2. The cylinder A, provided with downwardly-projecting pins d, which enter cavities in the bearing-disk b,-as specified.
